Why Zero Workers Died Carving Mount Rushmore With Dynamite

By Travelog Editorial Team ยท Updated August 8, 2026

Gutzon Borglum led a crew of 400 workers carving Mount Rushmore between October 1927 and October 1941. Dynamite removed roughly 90% of the approximately 450,000 tons of excavated granite, with charges precisely calculated to leave only 3 to 6 inches of rock over the final carved surface, the remainder finished by hand. Despite the inherent dangers of heights, explosives, and rockfalls, not a single worker died across the entire 14-year project. Borglum himself died in March 1941 before the monument's completion; work stopped that October.

Why zero fatalities across 14 years of dynamite work is a genuinely remarkable record

The combination of explosives, extreme heights, and rockfall risk over more than a decade makes this safety record a documented achievement, especially notable since it relied on worker skill and controlled procedure rather than the protective equipment modern construction would use.

Why "3 to 6 inches of rock" reflects genuine precision, not rough blasting

Dynamite charges were calculated specifically to leave only that thin margin of stone before hand-finishing began, worth understanding the explosive work itself as a precise, calculated process, not indiscriminate demolition followed by separate sculpting.

Why Borglum's death in March 1941 shaped how the monument ended up looking

Borglum died before the planned work was fully finished, so the monument as it exists today reflects where the project stood at his death and the subsequent October 1941 decision to stop rather than continue without him, not necessarily his complete original vision.

Why 90% dynamite versus hand-finishing tells the actual construction story

Most of the actual rock removal, roughly 450,000 tons of granite, came from dynamite blasting, worth understanding hand carving as the finishing step applied to a small remaining margin, not the primary method by which the mountain was shaped.

What This Means for Planning a Visit

The practical takeaway is that Mount Rushmore's construction story combines genuine engineering precision with a remarkable safety record, worth appreciating both alongside the finished monument.
